Cross folded envelope pamphlet

ABSTRACT

Pairs of envelopes formed by stitch glue and remoist glue applied in transverse lines to web, the web is split longitudinally, ribbons folded transversely to superimpose and crease, the crease is cut off to separate pages, folded again to form book, which is cut off transversely.

7 Claims, 13 Drawing Figures CROSS FOLDED ENVELOPE PAMPHLET FIELD OF INVENTION:

This invention relates to manufacture of multipage pamphlets containing envelopes on the inside pages, and has for its object to simplify and improve the construction and operation of manufactures of this character.

PRIOR ART:

This application isan improvement on copending application Ser. No. 94,052 filed Dec. 1, 1970 for Forming Multipage Pamphlet, filed by myself and Frederick Grainger.

BACKGROUND:

In said copending application, the envelopes are made from a continuous web fed from a roll, and folded longitudinally to prepare the envelope and the other pages, which are finally cut off transversely, to sever the pamphlet. The present invention can use precut sheets at high production speeds, and can employ transverse folding. It also allows the use of non standard cut off, and allows automatic trimming in both directions.

SUMMARY:

According to the present invention, envelopes are formed in stock along a path, the stock is folded to form a first crease, and then to form a second crease which is transverse, and which is severed to form separate superimposed sheets. These sheets are folded to form pamphlets with envelopes on the inside pages thereof.

Preferably the envelopes are formed by longitudinally extending pairs of pocket glue, and a transverse line of remoist glue. Preferably the first transverse crease abuts a stop, to determine the second crease. The fold of superimposed sheets is preferably along a previously applied line of stitch glue. Preferably two pamphlets are formed at the same time, in side by side relation, by slitting the stock longitudinally into ribbons.

In the Drawings:

FIG. I is an elevation of the envelope part of the pamphlet forming process;

FIG. 2 is a plan of the stock formed in FIG. 1;

FIG. 3 is an elevation of the stock shown in FIG. .2;

FIGS. 4,5,6, and 7 are elevations of the folding parts of the process;

FIGS. 8,9, and 10 are plans of the successively folded stock; and

FIGS. 11,12, and 13 are elevations respectively of the stock shown in FIGS. 8,9 and 10.

PREFERRED EMBODIMENT:

The paper stock 10 from any desired source such as a roll or stack of sheets, is fed along a continuous path, and a transverse line of stitch glue 12 is applied thereto a slit line 29, to divide the stock into two ribbons.

As shown in FIG. 4, the forward edge of both parts abuts a stop 33, and a folder 35 brings the forward flap 37 back over the pocket glue to form a crease 39. Then as shown in FIG. 5, the crease 39 abuts a stop 41, and a second folder 43 brings the flap 37 on over the rear end, forming a crease 45.

As shown in FIG. 6, the crease 45 enters a knife 47, which cuts off the folded end, and a third folder forms a central crease 51 in the superimposed sheets and along the stitch glue line 12, and delivers the finished book shown in FIG. 7.

FIGS. 8, 9, and 10 respectively show in elevation the structure respectively produced after the successive steps shown in FIGS. 4, 5, and 6.

FIGS. l1, l2 and 13 respectively show the elevational view of the stock shown in FIGS. 8, 9 and 10.

What is claimed is:

1. Method of producing pamphlets having envelopes therein, which comprises forming envelopes in stock along a path;

folding said stock to form a first crease;

folding the resultant first folded stock transversely to from a second crease;

severing said transverse crease to form separate superimposed sheets; and

folding said superimposed sheets to'form pamphlets having envelopes on inside pages thereof.

2. Method as claimed in claim 1, in which the envelopes are formed by longitudinally extending pairs of lines of pocket glue.

3. Method as claimed in claim 2, in which a transverse line of remoist glue is applied adjacent to said pairs of lines of pocket glue.

4. Method as claimed in claim 1, in which two pamphlets are formed at the same time, in side by side relation.

5. Method as claimed in claim 4, in which the stock is slit longitudinally into ribbons.

6. Method as claimed in claim 1, in which said first fold forms a transverse crease;

said crease abuts a stop; and

a folder forms said second crease as determined by said stop.

7. Method as claimed in claim 1, in which a transverse line of stitch glue is applied to the stock, and

said fold of the superimposed sheets is along said transverse line of stitch glue. 

1. Method of producing pamphlets having envelopes therein, which comprises forming envelopes in stock along a path; folding said stock to form a first crease; folding the resultant first folded stock transversely to from a second crease; severing said transverse crease to form separate superimposed sheets; and folding said superimposed sheets to form pamphlets having envelopes on inside pages thereof.
 2. Method as claimed in claim 1, in which the envelopes are formed by longitudinally extending pairs of lines of pocket glue.
 3. Method as claimed in claim 2, in which a transverse line of remoist glue is applied adjacent to said pairs of lines of pocket glue.
 4. Method as claimed in claim 1, in which two pamphlets are formed at the same time, in side by side relation.
 5. Method as claimed in claim 4, in which the stock is slit longitudinally into ribbons.
 6. Method as claimed in claim 1, in which said first fold forms a transverse crease; said crease abuts a stop; and a folder forms said second crease as determined by said stop.
 7. Method as claimed in claim 1, in which a transverse line of stitch glue is applied to the stock, and said fold of the superimposed sheets is along said transverse line of stitch glue.
